A two-lane road having a width of 9 metres was repaved, the lanes widened and painted with 20 cm wide, continuous edgelines instead of the conventional 10 cm wide intermittent lines. Compared with conventional repavement and repainting, the continuous edgeline was observed to give a larger variation of lateral position and lower speeds. The result should be a reduced risk of rutting. Because the area of the continuous edgeline is larger than that of the conventional line, visual guidance in night-time traffic will be improved. Road user interviews showed that the majority prefer continuous edgelines to intermittent lines. The conclusion drawn is that the wide, continuous edgeline is preferable and should replace the narrow intermittent line. (A)
